CVE-2026-63260

Name of the Vulnerable Software and Affected Versions Kibana (affected versions not specified)

Description An authenticated attacker with low-privilege access can cause a denial of service by sending a specially crafted, oversized request payload. This triggers uncontrolled resource consumption through excessive allocation, where the processing of user-supplied input requires memory allocation that exhausts the available heap memory in the Kibana process, leading to a system crash.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
